Almost all Americans consider themselves to be very patriotic, according to the Pew Research Center in Washington. But Pew has also found that Democrats and Republicans have discernibly different tendencies in the tenor of the patriotism.

Republicans tend to be far more likely than Democrats to believe “we all should be willing to fight for our country … right or wrong,” and to support the use of pre-emptive military force. They are less likely to care what the rest of the world thinks of us. (According to a recent Pew survey of citizens in 24 countries, the rest of the world prefers Obama to McCain.)

Over time, as Eric Liu and Nick Hanauer write in their book “The True Patriot,” those different tendencies have hardened into a caricature that “says the right loves America, and the left looks down on it. It says conservatives are proud to wave the flag and proclaim America to be the best, and liberals, embarrassed by the whole chest-thumping spectacle, complain about America’s errors.”

Hmm…you mean like these young patriots?

They can’t help it, either, so wishing they would act differently is hopeless.
